Solid State hard drives versus memory drives – the cost factor.
A memory drive (HDD)
A memory drive (HDD) has spinning disk and movable heads and data is written in a consistent manner with 0+1 characters which is easily filed and not difficult to retrieve. It has platter and actuator arms which is exclusive to this technology. This means it can store a lot of data for a less significant cost investment.
A solid state hard drive (SSD)
A solid state hard drive (SSD) actually has NO disk or movable mechanical components; however it is designed to store data using an integrated circuit assembly. This relatively new technology uses electronic interface compatible with traditional hard drive disk, therefore making it faster and permitting simple replacement in common applications. However, per unit of storage, SSDs are still far more expense that HDD – hence retrieving lost data is a fairly costly endeavour.
Solid state hybrid drives (SSHD)
Solid state hybrid drives (SSHD) combine features of both HDDs and SSDs in the same unit to improve performance of frequently accessed data. Very good as a backup media – larger sizes available.
USB Flash Drives
AKA memory sticks or thumb drives and can be considered the predecessor to the SSD only a much smaller version. Getting larger in size – common are 8 to 64 GB in size – allowing to act as good backup media.
Typical problem now is that people have a lot of data and these can be lost or misplaced with data on them.
